What causes the stem to be redish? Is this normal ...
NobodysBudsanswered grow question 3y ago
red petioles and red stems are 2 different things.
red petioles can come from the LED lights or a nute deficiency... gotta check the leaf chart.. (google and save animage of one for your own reference) -- P-deficiency.
So, i'd consider what you currently feed, any experience... don't blast it with P blindly as it could easily be casued by intense LED lighting and some plants just react that way to LED it seems. i've tried to give more P and it does nothing for it and would often bring out some symptoms of overfeeding.. so i was pretty sure it was teh LED in my context... rule things out and don't react too quickly.
for future reference.. streaks of read in stems.. not petioles.. are a symptom of sulfur-deficiency

Hi, Red or purple stems in cannabis can be a sign of stress, nutrient deficiency, pathogens, or simply genetics.

Deficiency and assimetric developmentMy girls seem to have a deficiency, strangely enough, the gal with the most signs of deficiency is doing the best in bud production. Any ideas on what is going on here and what is the cause of the deficiency?

My plant is twisting itself..Woke up this morning to find my plant dancing to "Twist Again".
Is this due to airflow setup inside the tent? Perhaps the lighting's intensity?

Leaf problem and purple stemsHi,
I have a problem with my auto.
I have purple stems and problems with the leaves.
The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem.
Is it a nitrogen deficiency ?
Thank you for the answerLeaves. Curl up

Is it nutrients? Light?What can this be? The stem is red, and I thought it could be over lighting (I had 2 LEDs of 200 W each), so I removed one of it. But now I am also wondering that it can be nutrients, no? If so, how can I solve it? Let me know what you think. It's an autoflower - 7 weeek.Leaves. Curl down
